FLUID-PROPELLED MACHINE.

To all whom t may concern.

Be it known that I, JOHN ARTHUR HAM- ILTON OR-EILLY, of the city of Winnipeej, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Fluid- Propelled Machines, of which the following` is a specification.

The invention relates to a machine propelled by a fluid, and the object of the invention is to provide a machine of this class .wherein a rotary motion is acquired by Vthe flow of a fluid under the combined action of radial, tangential and axial forces in a spiral path passing in the direction of the axis of the rotating system.

A further object of the invention is to supply a machine of this class comprising but few parts which can readily be put together.

With the above objects in View the invention consists essentially in a rotatably mounted axle, a plurality or series of spiral paths surrounding the axle and passing in each instance in the direction of the axis of the rotating system and means for passing fluid into the -varous spiral paths, the parts being arranged and constructed as hereinafter more particularly described.

Figure 1 is a side view'of the machine. Fig. 2 is a vertical sectional view centrally through the same. Fig. 3 is an end View of the same with one of the end plates removed. Fig. 4f is a detailed side view of two of the cylinders and a portion of the axle, the outer of the cylinders being broken away to expose construction.

In the drawing like characters of reference indicate corresponding parts in each figure.

1 represents a. permanent base piece snitably bolted to a flooring and carrying a cylindrical easing 2 which incloses the cylinders later referred to. The ends of the casing are closed by end plates 3 and 4l permanently bolted to the casing and base piece. y 5 is a shaft rotatably mounted in the end plates and centered in the casing. The shaft carries in the present instance tive cylinders` 6, 7, 8, 9 and 1.0, of varying diameter, which cylinders are placed one around the other and are designed so that the outer on-e makes a fluid tight contact at 1l with the inclosing casing.

Packing strips 12 are inserted between Specification of Letters Patent.

the face of the outer cylinder and the casing.` The inner cylinder is cored out centrally to receive the shaft and has the outer or circumferential face provided with a deep spiral thread 13 which passes the full length `of the cylinder in the direction of the axis of rotation of the shaft 5. The cylinders 7, 8 and t) have their outer or circumferential faces each provided with deep spiral threads 141, 15, and 1G, respectively, the threads also passing in the direction of the axis of rotation of the shaft 5. The outer cylinder 10 has its circumferential face fitting within the casing 11 as already explained. Each of the cylinders 7, S, 9 and 10 are cored out. centrally and supplied on their inner faces with shallow internal spiral threads 7, S', 9', and 10', passing also in the direction of the axis of rotation of the shaft These threads are ar anged to receive the apices of the threads 13, 111, 15 and 1G thereby allowing the cylinder 7 to be screwed on to the cylinder the cylinder 8 to be screwed on to the cylinder 7, the cylinder t) to be screwed on to the cylinder S and the cylinder 10 to be screwed on to the cylinder 9. Further as the external threads 13, 14, 15 and 16 are deep threads, and those 7, S', 9', and 1.0 are shallow internal threads, .l form in this way a number of spiral paths A, B, C and D between the cylinders, which paths all pass in the direction of the axis of rotation of the shaft 5, the inlets to the paths being at a, 7), c, and d, at one side of the rotor built up b v the cylinders, while the outlets arc located at d 7) c and cl Chests are formed between the ends of the rotor and the end plates El and ll at 17 and 18, and an inlet pipe 1f) opens to the chest 17, while an outlet pipe 9() passes fro-m the chest 18. The rotors, or in other words, the cylinders are connected permanently with the shaft 5 by collars Q1 and 22 bolted to the shaft and fitted with radially extending arms 28 in turn bolted permanently to the ends of the cylinders.

The fluid entering the chest 17 under pressure through the pipe 19 finds its way into the paths A, 13, C and l), and finally is expelled into the chest 1S from which it is freed through the pipe 20. The rotating motion imparted to the rotor which comprises in the present instance the cylinders 6, 7, 8, 9 and 10 depends on the adhesive and viscous action of the fluid passed through the rotor in the spiral paths.V

I desire to point out that the cylinders may be increased in length or the pitch of the threads 18, 14, 15 and 16 may be decreased as desired to give any required length of path and if it is not desirable to increase the length of the cylinders or decrease the pitch of the threads further than a certain amount the increased path can be obtained by reversing the direction of the spiral paths formed between the successive cylinders and connecting them at the end so that the fluid is compelled to flow first in one direction and then in the other throughout the complete system of paths so formed around the axis of rotation.

I wish to point out that the machine is reversible, this depending on whether the fluid is admitted through the openings a, Z2, 0, and cl,'or through tho-se a 44 bf, C( 0/77 C if-77 What I claim as my invention is 1. A fluid propelled machine comprising, a rotatably mounted shaft, a rotor fixed on the shaft and formed from a number of cylinders of different diameter threaded one on to the other, the threads being constructed to form between the cylinders spiral paths passing in the direction of the axis of the shaft, and means for admitting a fluid to the paths so formed and for discharging it therefrom, as and for the purpose specified.

2. A fluid propelled machine comprising a suitably mounted rotatable shaft, a number of cylinders of equal length but varying in vdiameter centered on and rotatable with Ythe shaft and having the cylinders of smaller diameter contained within those of larger diameter, said cylindersl being further arranged to thread one. on to the other, the threads on the adjacent external and internal faces being constructed to form spiral paths between the cylinders passing in the direction of the axis of the shaft, an inclosing casing, and means for admitting fluid to the aforesaid paths and for discharging it from the same, as and for the purpose specified.

3. A fluid propelled machine comprising, a rotatably mounted shaft, a rotor fixed on the shaft and formed from a number of cylinders of different diameter threaded one on to the other, there being spiral paths formed between the several cylinders, and means for admitting a fluid to the said paths and for discharging it therefrom, as and for the purpose specified.

ZL. A fluid propelled machine comprising, a rotatably mounted shaft, a number of cylinders of equal length but varying in diameter centered on the shaft and fitted one within the other, the said cylinders having the adjacent internal and external circumferential faces provided with grooves and project-ions fitting the one with the other to form a number of paths between the cylinders passing in the direction of the axis of the shaft, means for passing a fluid into the paths so formed and for expelling it from the same, as and for the purpose specified.

5. In a fluid propelled machine, a rotor formed from a plurality of internally and externally threaded cylinders of different diameter threaded one onto the other, the threads on the adjacent external and internal face being constructed to form spiral paths passing in the direction of the axis of the rotor, as and for the purpose specified.

6. A fluid propelled machine comprising a suitably mounted rotatable shaft, a number of cylinders of equal length but varying diameter centered on and rotatable with the shaft and having the cylinders of smaller dimension contained within those of larger diameter, said cylinders being further arranged to thread one onto the other, the threads on the adjacent external and internal faces being constructed to form spiral paths between the cylinders passing in the direction of the axis of the shaft, an inclosing casing receiving the cylinders and forming chests at the ends thereof, said casing supporting the shaft rotatably and the chests opening` to the spiral paths and means for passing the fluid into one of the chests and for expelling it from the other, as and for the purpose specified.
